move air with no moving parts
That would be a passive cooling system.

At what point do we add active cooling to phones?
I don’t mean that as a joke, there are some really interesting systems being developed (which are functional) that are extremely tiny that can move air with no moving parts, they’re being developed for exactly this sort of use in electronics.
So, no need for a fan that wears down, creates noise, etc.
The biggest issue would be keeping the air channel free of dust and debris, if they can figure that out, then adding a few millimetres of thickness and a small weight increase in order to accommodate future higher capability processors seems entirely acceptable.

No? Passive systems don’t do anything to cool other than simply exist.
These systems use energy and are deliberately activated to influence how heat is transferred. That’s the difference of active vs passive.

Hmm that’s interesting, how does this system use energy to move heat around then, if there are no moving parts? Not a rhetorical question, I’m genuinely curious about this system, would you jave more info or links to share?

I know it’s Linus, but this is the video I first learned about piezoelectric blowers: youtu.be/vdD0yMS40a0?si=MrmBK_b6SbtYG5iF
It’s pretty rad. And already exists.

This is some company’s page, but they have a pretty good demonstration of one common method

We already have. It’s called a Nintendo Switch

This sounds promising. Dustproof. I dont think waterproofing the air channel will be necessary. This can be used as a way to create a channel for air to pass through without compromising the waterproof seal for the phone internals. The air channel can be a pass through and offers a big benefit in cooling. If there is blockage or damaged fins(I think they are vibrating fins.), then the phone will get warm and automatically throttle. A repair will not be needed unless you want the full performance. I live in the hot desert, and active cooling would be a dream come true. Every high-end phone gets hot to the touch from using GPS or streaming outside.
